Periodic inspection
• After being used for a long period of time, the parts

usage.

that you have a inspection (charges apply) performed
by the dealer where you purchased the unit, etc.

• Perform high-pressure cleaning for the heat
exchanger.
If commercially available detergent (strong alkaline
or acid cleaning agent) is used, the surface treatment
of the heat exchanger will deteriorate, which may
degrade the self cleaning performance. For details,
contact our sales department or the dealer where
you purchased the unit.
